Embodiment 1

[0053] attached Figure 6 The detailed flowchart of the network access method provided by the embodiment of the present invention. In this embodiment, the network access device is a GGSN.

[0054] Step 601, when the user needs to access the network, send a network access request message to the GGSN through the browser or other client software in the host.

[0055] Optionally, the network access request message is a PDP context (Packet Data Protocol context) activation request message or an IP-CAN Bear activation request message. The network access request message carries user information of the user, such as a user identifier, such as a Mobile Subscriber Integrated Services Data Network Number (MSISDN, Mobile Subscriber International ISDN / PSTN number), an International Mobile Subscriber Identity (IMSI, International Mobile SubscriberIdentification Number), optionally, user information also includes: the access point name (APN, Access Point Name) that user needs to visit, the...

Embodiment 2

[0092] The embodiment of the present invention provides a method for PCEF to control and manage user traffic after the user accesses the network. The flow chart is shown in the attached Figure 7 shown. Among them, the PCEF and the network access device are connected to transmit the data packets of the control plane through the Gx interface in addition to transmitting the data packets of the service plane through the Gi interface. In this embodiment, the network access device uses the GGSN as an example for illustration.

[0093] Step 701, when the GGSN allows the user to access the network, establish a session connection of the Gx interface between the PCEF corresponding to the user and the GGSN, establish a session connection of the Gx interface between the PCEF corresponding to the user and the PCRF, and establish the corresponding The session connection of the Gy interface between the PCEF and the OCS.

[0094] Step 702, the PCEF calculates the quota usage corresponding ...

Abstract

The invention discloses a network access method, system and equipment, used for solving the problem that a policy and charging enforcement functional (PCEF) entity in the prior art can not reliably obtain user information in time, therefore network flow of a user cannot be controlled and managed effectively. The method comprises the following steps: the PCEF receives a session request message sent by network access equipment through a Gx interface between the PCEF entity and the network access equipment, wherein the session request message is sent after the network access equipment receives a network access request message sent by a user; the PCEF entity acquires and stores user information through analyzing the session request message; a policy corresponding to the user is requested for the PCRF entity according to the user information, and the policy is saved; and the PCRF entity carries out management and control on the flow of the user according to the user information and the policy. Through adoption of the scheme, the reliability and timeliness of the user information obtained by the PCEF entity can be improved.

Description

technical field [0001] The invention relates to the technical field of computer and communication, in particular to a network access method, a network access system and equipment. Background technique [0002] Third Generation Partnership Project (3GPP, Third Generation Partnership Project) specifications With the development of wireless networks becoming more and more perfect, more and more operators use the 3GPP specifications to manage networks. The network element equipment related to operator network management in the 3GPP specification is attached figure 1 shown. [0003] attached figure 1 A gateway (GW, gateway) in is used as an access point for users to access the network, and a Policy and Charging Enforcement Function (PCEF, Policy and Charging Enforcement Function) is a functional module in the GW. The PCEF interacts with the policy and charging rule entity (PCRF, Policy and Charging Rule Function) through the Gx interface. According to the user's subscription ...
